My rough notes for this meeting are available on the WG21 wiki here
<https://wiki.edg.com/bin/view/Wg21telecons2025/SG16Teleconference2025-11-19>.

The P3695 GH issue <https://github.com/cplusplus/papers/issues/2325> has
been updated to record the two polls that were taken which included the
forwarding poll. This proposal is now in EWG's hands and labels have
been adjusted accordingly.

The P3688 GH issue <https://github.com/cplusplus/papers/issues/2318> has
been updated to note that SG16 has started discussion, but not yet
concluded it. My intention is to continue discussion of this paper
during the next SG16 meeting on 2025-12-10.

Tom.
